Raiders defensive line coach Terrell Williams has left the Raiders and joined the University of Florida as its defensive line coach, according to a report Saturday.

Williams spent the past three seasons with the Raiders. He is the first assistant coach from fired coach Dennis Allen’s staff to leave for another job. FootballScoop.com was the first to report Williams’ departure.

More assistant coaches likely are on their way out in the coming days and weeks, especially if the Raiders don’t make Tony Sparano the full-time head coach. Sparano replaced Allen four games into last season, and he is among numerous candidates interested in the Raiders job.

Sparano is the only Raiders coach with a contract for 2015. If he gets bypassed for the full-time head coaching job, it’s likely that more, if not all, of the Raiders assistant coaches, whose contracts are set to expire later this month, don’t return next season.

Already, Raiders defensive coordinator Jason Tarver has been linked with job openings at Texas A&M — that defensive coordinator opening since has been filled — and the 49ers.
